As in the case of other bee pollen constituents, the mineral composition is greatly affected by several factors, mainly soil, climate, geographical origin and botanical species (Liolios et al., 2019, Taha, 2015, Yang et al., 2013), since the plants accumulate different amounts of mineral salts.
Herbal Medicine
Plants are rich in a variety of compounds. Many are secondary metabolites and include aromatic substances, most of which are phenols or their oxygen-substituted derivatives such as tannins (Hartmann 2007; Jenke-Kodama, Müller, and Dittmann 2008). Many of these compounds have antioxidant properties (see Chapter 2 on antioxidants in …

Silicon (Si) is the second most abundant element in the earth's crust, almost exclusively found in the form of silicon dioxide (SiO 2) in association with a wide array of Si-bearing minerals in crystalline, poorly crystalline, and amorphous phases (Sommer et al., 2006).In the early 1900s, Si was recognized as one of the 15 elements needed for plant life …
Nutrient Acquisition by Plants | Organismal Biology
Soil Composition Influences Nutrient Availability to Plants. The information below was adapted from OpenStax Biology 30.3. Even though most plants are autotrophs and can generate their own sugars from carbon dioxide and water, they still require certain ions and minerals from the soil. This process is mediated by root hairs, which are ...
